The component (a) in the preparation contains a mixture of two or more amino acids or derivatives thereof; the component (b) in the preparation contains a mixture of three or more extracts from plants. There are several plant extracts used in this invention such as the extract of  ginseng  radix, the extract of  ginkgo biloba  leaf, the extract of Silibinin, the extract of barbury wolfberry fruit and tea polyphenols. The invention also relates to the biological activities of said preparation, such as the liver protection from chemical injury, the tolerance enhancement of hypoxy and the rapid decrease till elimination of the blood alcohol content.

FIELD OF THE INVENTION

The invention relates to preparations for dietary, food supplement ormedical purposes and more specifically to a preparation or a compositioncomprising amino acids and several plant extracts and its activity inthe alcohol detoxification. The composition of the invention can be usedin the protection of chemical liver injury, in hypoxic toleranceenhancement, in the in vivo ethanol content quickening removal and thereduction and viability enhancement in the anoxic environment.

BACKGROUND OF THE INVENTION

It is known that L-ornithine and citrulline are involved in at leastthree important annular metabolic pathways in the human body. The threemetabolic pathways are respectively the urea circulation, the citricacid circulation and the nitric oxide circulation. By taking L-ornithineand citrulline, the endogenous biomolecular messenger nitrogen monoxide(NO) can be obtained through the related metabolic pathway. The bloodcirculation system in the human body cannot function without thevasodilation function of NO, the endogenous NO has the adjustment andcontrol function on multiple physiological functions, for example, theenergy among nerve synapses can be adjusted; and the learning andmemorization process can be adjusted, etc.

The endogenous NO in the human body is generated by catalyzingL-arginine (L-Arg) to be decomposed by nitric oxide synthetase (NOS).L-Arg is an important substance in the human body, in addition to the NOgeneration and the participation in protein synthesis, L-Arg is also theprecursor of urea, praline, agmatine, polyamine and the like and canstimulate the secretion of hormone, such as auxina and insulin todirectly influence the health of the human body. When the human body isunder special stress conditions, for example, under hypoxia condition,the endogenous NO in the human body is insufficient, which can causealtitude reaction or sickness.

Besides the effects of altitude reaction and ischemia-reperfusion injuryprevention and treatment and cardio-cerebral-vascular system and immunesystem protection, L-Arg can prolong the mice burden swimming time andreduce the accumulation of lactic acid caused by anaerobic glycolysis,therefore to perform the anti-fatigue function.

However, because the half-life period of the taken L-arginine (L-Arg) isvery short (only approximately one hour) the direct replenishment ofarginine cannot effectively increase the arginine concentration in theblood and the cells.

It is known that L-citrulline (L-cit) is a non-protein amino acid andhas a plurality of important physiological functions, such as freeradical removal, vasodilatation and blood pressure stabilization,moreover, the endogenous arginine (L-Arg) and NO can be continuallygenerated through the L-cit-NO circulation in the human body to ensurethe endosomatic arginine level to be obviously enhanced and to maintainat a higher foundation level simultaneously, thus, the hypoxia toleranceof the organism is enhanced.

L-ornithine is an important non-protein amino acid existing in tissuesand cells and is also the precursor substance for metabolism ofarginine, citrulline and other amino acids. L-ornithine almostparticipates in the entire processes of urea cycle activation andammonia disintoxication, facilitates the synthesis of carbamyl phosphatesynthetase and glutamine and increases the disintoxication function ofthe liver; therefore, L-ornithine is significant to the liver cells inthe human body.

The ginseng siccus extract comes from the dried root and radix andrhizomea ginseng of Panax ginseng C.A Mey. or radix and rhizomea ginsengrubra Panaxoside. The main active ingredient, the ginseng extract canobviously protect the liver cell from chemical injury; the animalexperiment proved that panaxoside can also protect the brain cell fromthe ischemia-reperfusion injury and has obvious improving effect on thechemical learning and memorization functional disorder of animals.

The ginkgo siccus extract comes from the folium ginkgo of ginkgo bilobaL. The ginkgo siccus extract can prevent the abnormal metabolism of NOby reducing the Ca²⁺ level, protects from the glutamate neurotoxicity,antagonizes the platelet activating factors and has the protectivefunction on the brain tissue with hypoxic-ischemic encephalopathy,protects the liver and has transaminase reduction effects.

Silibinin, coming from the seed of Silybum marianum (L.), is a powerfulfree radical scavenger and an inhibitor of lipid peroxidation that hasprotective, healing and detoxification effects on the liver. Silibinin'sactivities on the enzyme enhancing and membrane stabilizing of the livercell helps in reducing and repairing the damage to the liver thatalcohol, a high fat diet, the tobacco consumption and many prescriptionmedicines can causes.

The extract of fructus lycii comes from the Fructus jujubae of Lyciumbarbarum L. The fructus lycii is the usual traditional Chinese medicinefor liver and kidney tonification, the color is scarlet and the flavoris sweet. Modern medical research have proven that the fructus lyciicontains betaine, polysaccharide, crude fat, crude protein, carotene,vitamin A, vitamin C, vitamin B1, vitamin B2, calcium (C), phosphorus(P), Ferro (Fe), zinc (Zn), manganese (Mn), linoleic acid and othernutrient contents. Extract of fructus lycii has promotes thehematopoietic function and has anti-ageing, anti-mutation, anti-tumor,anti-fatty liver and blood glucose level reduction functions. Theherbalist doctor often uses fructus lycii to treat Yin deficiency ofliver and kidney, soreness and weakness of waist and knees, dizziness,morbid forgetfulness, blurred vision, hypopsia and overflow of tears,thirst quenching, spermatorrhea and other illness symptoms. For thepeople having a kidney deficiency, fructus lycii is undoubtedly a kindof healthcare nutriment. Fructus lycii is the optimum selection forhealth preservation from ancient time to modern time and has the lifelengthening function.

Tea polyphenols is the general term of the polyphenol substancescontained in the tea leaf, including flavanol class, anthocyanin class,anthoxanthin class, flavonol class, phenolic acid class and the like,wherein, the flavanol substance (catechin) is the most important. Teapolyphenols is also called tea tannide or tea tannin, which is the majorcomponent which forms the colour, smell and flavour of the tea leaf andis also the major component having the healthcare function in the tealeaf. Tea polyphenols has detoxification and radio resistance effectsand can effectively block radio material from invading the bone marrowand can cause strontium (Sr) 90 and cobalt (Co) 60 to be quicklydischarged from the body, therefore, it is honoured as RadiationInvincible Opponent and builds a defensive line for resisting toradiation injury for the health of human. The tea polyphenols have thecerebral stroke prevention, intestine and stomach tension relieving anddigestion aiding functions and can clean the superfluous free radical inthe human body, inhibit lipid peroxidation, enhance immunologic functionand postpone senility.

The Applicants have studied specific plants and several amino acids andtheir potential application in alcohol detoxification. Surprisingly itwas found that the administration of the preparation according to theinvention among other unexpected biological activities dramaticallyreduces the blood alcohol content in the body.

The synergy action of the preparation according to the invention seemsto be separated by any other pharmacological action (see the Examples).

The present invention provides for a preparation comprising thecombination of a composition (a) containing amino acids consisting ofcitrulline and ornithine hydrochloride and/or derivatives thereof and acomposition (b) containing a mixture of ginseng or ginseng extract,ginkgo biloba leaf extract and silibinin extract, optionally with asuitable excipient.

According to the present invention, it is intended by citrulline and/orornithine hydrochloride “derivatives” any structural as well asfunctional derivatives thereof. Derivatives thereof may be for exampleprecursors of said amino acid as well as by products thereof (alsodefined as degradation products).

“Precursors of amino acids” are metabolites originated from metabolicpathways such as the glycolysis, the TCA cycle (tricarboxylic acidcycle) or the pentose phosphate pathway. More specifically theseprecursors include α-ketoglutarate, 3-phosphoglycerate, oxaloacetate,pyruvate, phosphoenolpyruvate and erythrose 4-phosphate, ribose5-phosphate and any other molecule upstream or downstream of the wayleading to these metabolic precursors.

“Degradation products of amino acids” are amino acids that may undergoan initial degradation that removes amino group either by transaminationor by oxidation. The ammonium ion is recovered and recycled to formanother amino acid or eliminated. The carbon skeleton obtained after theremoval of the amine group can also be recovered to synthesize thecorresponding amino acid or as a precursor for the synthesis ofcarbohydrates (in the case of amino acids glycoforms) or converted intoacetyl-CoA for fatty acid synthesis (i.e. ketogenic fatty acids).

Also encompassed by the definition of the terms derivatives ofcitrulline and/or ornithine hydrochloride are pharmaceuticallyacceptable salts thereof. According to the present invention,pharmaceutically acceptable salts are produced from acidic inorganic ororganic compounds, or alkaline inorganic or organic compounds. As usedherein, the phrase “pharmaceutically acceptable salt” refers to a saltthat retains the biological effectiveness of the free acids and bases ofa specified compound and that is not biologically or otherwiseundesirable. The pharmaceutically acceptable salts of the amino acidsaccording to the invention are acid addition salts with pharmaceuticallyacceptable acids.

A desired salt may be prepared by any suitable method known in the art,including treatment of the free base with an inorganic acid, such ashydrochloric acid, hydrobromic acid, sulphuric acid, nitric acid,phosphoric acid, and the like, or with an organic acid, such as formicacid, acetic acid, maleic acid, succinic acid, mandelic acid, maleicacid, fumaric acid, malonic acid, pyruvic acid, oxalic acid, glycolicacid, salicylic acid; a pyranosidyl acid, such as glucuronic acid orgalacturonic acid; an alpha-hydroxy acid, such as citric acid ortartaric acid; an amino acid, such as aspartic acid or glutamic acid; anaromatic acid, such as benzoic acid or cinnamic acid; a sulfonic acid,such as methanesulfonic acid, p-toluenesulfonic acid or ethanesulfonicacid; or the like.

In the present invention the preferred ammonium salts are derived fromhydrochloric, hydrobromic, methanesulfonic, acetic, propionic, benzoic,citric, tartaric, malic, maleic, fumaric, lactic, nitric, and phosphoricor succinic acid.

Generally, the salts are prepared by reacting the free base withstoichiometric amounts or with an excess of the desired salt forminginorganic or organic acid in a suitable solvent or various combinationsof solvents. For example, the free base can be dissolved in a mixedaqueous solution of the appropriate acid and the salt recovered bystandard techniques, for example, by evaporation of the solution.Alternatively, the free base can be charged into an organic solvent suchas a lower alkanol, symmetrical or asymmetrical ethers containing 2 to10 carbon atoms, an alkyl ester, or mixtures thereof, and the like, andthen it is treated with the appropriate acid to form the correspondingsalt. The salt is recovered by standard recovery techniques, forexample, by filtration of the desired salt from the mixture, or it canbe precipitated by the addition of a solvent in which the salt isinsoluble and recovered there from.

Examples of suitable inorganic and organic solvents for performing thevarious reactions include any inorganic or organic solvent that does notadversely affect the reactants or the resulting product, includinghalogenated solvents such as methylene chloride, chloroform, ethersolvents such as diethyl ether, and other solvents such astetrahydrofuran, dioxane, diglyme, cyclooctane, benzene or toluene,heptane, cyclohexane, aliphatic as well as cycloaliphatic and aromatichydrocarbon solvents, water, acidified aqueous solutions, mixed organicand inorganic solutions, ethyl acetate, propyl acetate and mixturesthereof.

Also encompassed by the present invention are salts formed from acidicprodrugs, such as phosphates, and alkaline inorganic or organiccompounds. Preferred inorganic cations comprised in the salts arelithium, sodium, potassium, rubidium, ammonium, calcium, magnesium, zincand manganese. Production of phosphate salts are described in e.g. G. R.Pettit et al. Anti-Cancer Drug Design 16 (2001) 185-193.

Usually salts also include those formed from acidic prodrugs and organicamines, including, but not limited to, imidazole and morpholine.Alkaline amino acid salts may also be used.

Preferred salts according to the invention are for example CitrullineMalate which is a combination of the amino acid citrulline and theorganic salt malate: L-Citrulline DL-malate. As well as D-Citrulline (1)also known as: (R)-2-Amino-5-ureidopentanoic acid, DL-Citrulline (1)also know as: (±)-2-Amino-5-ureidopentanoic acid,DL-2-Amino-5-ureidovaleric acid; L-Citrulline (3) L-Citrulline7-amido-4-methylcoumarin hydrobromide (1) also known as : L-Citrulline4-methyl-7-coumarinylamide hydrobromide, L-Citrulline-4,4,5,5-d4 (1);N-2,4-DNP-DL-Citrulline (1); Thio-L-citrulline (2) or L-Citrullinemonohydrochloride. Pharmaceutical salts of ornithine are alsocontemplated such as ornithine alpha-ketoisocaproate, ornithinealpha-ketoglutarate (O alpha KG), ornithine chlorhydrate.

The term “citrulline and/or ornithine hydrochloride derivatives”designates, according to the invention, in particular the [alpha]-aminoacids occurring in nature, but moreover also includes their homologues,isomers, analogs all those terms are referred under the definition ofderivatives as described above. Enantiomers can be mentioned as anexample of isomers. Analogs can be, for example, amino acids providedwith protective groups.

Furthermore, since an inherent problem with native peptides (in L-form)is the degradation by natural proteases, the amino acids of theinvention may be prepared in order to include D-forms and/or“retro-inverso isomers” thereof.

A higher biological activity is predicted for the retro-inversocontaining amino acid when compared to the non-retro-inverso containinganalogue owing to protection from degradation by native proteinases.Furthermore they have been shown to exhibit an increased stability andlower immunogenicity [Sela M. and Zisman E., (1997) Different roles ofD-amino acids in immune phenomena—FASEB J. 11, 449].

Retro-inverso amino acids are prepared as described for example in Selaand Zisman, (1997).

Also encompassed by the definition of derivatives are modifications ofthe “citrulline and/or ornithine hydrochloride” including in vivo or invitro chemical derivatization, e.g., acetylation or carboxylation. Alsoincluded are modifications of glycosylation, e. g., those made bymodifying the glycosylation patterns of an amino acid during itssynthesis and processing or in further processing steps, e. g. mammalianglycosylating or deglycosylating enzymes. Also included are sequenceswhich have phosphorylated amino acid residues, e. g., phosphotyrosine,phosphoserine, or phosphothreonine.

In the preparation according to the invention, no carrier orpharmaceutically acceptable carrier or suitable excipients are oftenrequired to be added. However, suitable excipients may optionally beadded.

Examples of suitable excipients of this invention include, but are notlimited to, anti-adherents, binders (e.g., macrocrystalline cellulose,gum tragacanth, or gelatin), coatings, disintegrants, fillers, diluents,softeners, emulsifiers, flavoring agents, coloring agents, adjuvants,lubricants, functional agents (e.g., nutrients), viscosity modifiers,bulking agents, glidiants (e.g., colloidal silicon dioxide) surfaceactive agents, osmotic agents, diluents, or any other non-activeingredient, or combinations thereof.

The emulsions can also contain anionic,nonionic, cationic or amphoteric surfactant(s).

Surprisingly, it has been observed that the preparation of the inventionis also effective in the treatment or prevention of headache ormigraine.

A person suffering from headache can experience pain in several areas ofthe head, including a network of nerves that extends over the scalp andcertain nerves in the face, mouth, and throat. The muscles of the headand the blood vessels found along the surface and at the base of thebrain are also sensitive to pain because they contain delicate nervefibers. The bones of the skull and tissues of the brain itself do nothurt because they lack painsensitive nerve fibers. The ends of thesepain-sensitive nerves, called nociceptors, can be stimulated by stress,muscular tension, dilated blood vessels, and other headache triggers.Vascular headaches (such as migraines, for instance) are thought toinvolve abnormal function of the brain's blood vessels or vascularsystem; muscle contraction headaches appear to involve the tightening ortensing of facial and neck muscles; while traction and inflammatoryheadaches are symptoms of other disorders, ranging from brain tumor tostroke or sinus infection. Some types of headache are signals of moreserious disorders: sudden, severe headache; headache associated withconvulsions; headache accompanied by confusion or loss of consciousness;headache following a blow on the head; headache associated with pain inthe eye or ear; persistent headache in a person who was previouslyheadache free; recurring headache in children; headache associated withfever; headache that interferes with normal life.

Headaches are diagnosed as vascular, muscle contraction (tension),traction or inflammatory headaches.

The most common type of vascular headache is migraine. Migraine is themost common neurological condition in the developed world. It affectsabout 10% of the population and is more prevalent than diabetes,epilepsy and asthma combined. Migraine is more than just a headache. Itcan be a debilitating condition which has a considerable impact on thequality of life of sufferers and their families. Attacks can becompletely disabling, forcing the sufferer to abandon everydayactivities for up to 3 days. Even in symptom free periods, sufferers maylive in fear of the next attack. The pain of a migraine headache isoften described as an intense pulsing or throbbing pain in one area ofthe head. It is often accompanied by extreme sensitivity to light andsound, nausea, and vomiting. Migraine is three times more common inwomen than in men. Some individuals can predict the onset of a migrainebecause it is preceded by an “aura” visual disturbances that appear asflashing lights, zig-zag lines or a temporary loss of vision. Peoplewith migraine tend to have recurring attacks triggered by a lack of foodor sleep, exposure to light or hormonal irregularities (only in women).Anxiety, stress or relaxation after stress can also be triggers. Formany years, scientists believed that migraines were linked to thedilation and constriction of blood vessels in the head. Investigatorsnow believe that migraine is caused by inherited abnormalities in genesthat control the activities of certain cell populations in the brain.There are two ways to approach the treatment of migraine headache withdrugs: prevention of the attacks or the relief of the symptoms duringthe attacks. Many people with migraine use both approaches by takingmedications originally developed for epilepsy and depression to preventfuture attacks, and treating attacks when they happen with drugs calledtriptans that relieve pain and restore function.

After migraine, the most common type of vascular headache is the toxicheadache produced by fever. Pneumonia, measles, mumps, and tonsillitisare among the diseases that can cause severe toxic vascular headaches.

Toxic headaches can also result from the presence of foreign chemicalsin the body.

Other kinds of vascular headaches include “clusters,” which causerepeated episodes of intense pain, and headaches resulting from a risein blood pressure. Cluster headaches, named for their repeatedoccurrence in clusters over weeks or months at roughly the same time ofday or night, begin as a minor pain around one eye, eventually spreadingto that side of the face. The pain quickly intensifies, compelling thevictim to pace the floor or rock in a chair, for instance. Othersymptoms include a stuffed and runny nose and a droopy eyelid over a redand weeping eye. Cluster headaches last between 30 and 45 minutes butthe relief people feel at the end of an attack is usually mixed withdread as they await a recurrence. Clusters may mysteriously disappearfor months or years. Many people have cluster bouts during the springand fall. At their worst, chronic cluster headaches can lastcontinuously for years. Cluster attacks can strike at any age butusually start between the ages of 20 and 40. Unlike migraine, clusterheadaches are more common in men and do not run in families.Paradoxically, both nicotine, which constricts arteries, and alcohol,which dilates them, trigger cluster headaches. The exact connectionbetween these substances and cluster attacks is not known. In oneembodiment of the invention, suppression of cortical spreadingdepression (CSD) has not been reported.

Thus, the present invention concerns the use of the preparationaccording to the invention for the prevention, alleviation or/andtreatment of headache, especially chronic headache such as migraine.Further, the present invention concerns the use of the preparationaccording to the invention for the prevention, alleviation or/andtreatment of all types of painful conditions associated with or/andcaused by CSD, such as, but not limited to, cerebral ischemia duringstroke or cardiovascular surgery, for instance, traumatic brain injury,subarachnoid haemorrhage or transient global amnesia. Preferred, but notlimited to, is the use of the preparation of the invention for theprevention, alleviation or/and treatment of chronic headache associatedwith or/and caused by CSD such as migraine or other forms of chronicheadache of both central and peripheral origin such as, but not limitedto, cluster headache, tension-type headache or secondary headachesassociated with over use of medication, cranial neuralgias, brain traumaand vascular or metabolic disorders, for example. Especially preferredis the treatment of acute migraine.

Dosage Design: Three sample dosage groups with the dosage of 200mg/kg/d, 400 mg/kg/d (equivalent to ten times the recommended intakingamount for an adult per kilogram of the body weight per day) and 1200mg/kg/d, a blank control group and a model control group are designed.The test objects in the sample dosage groups are prepared with doubledistilled water, the test objects in the blank control group and themodel control group are administered with double distilled water, 20ml/kgb wt of dosage is respectively drenched into the stomachs of themice in each group per day for continuous 30 days. 10 ml/kg b.wt. of 65percent of ethanol is respectively drenched into the stomachs of themice in the model control group and the sample dosage groups after twohours after the test object is administered for the last time, doubledistilled water is administered into the mice in the blank controlgroup, the animal are sacrificed after fasting for six hours for variousbiochemical index determination and liver pathological histologyexamination.

Experimental Method

Determination of Biochemical Index: 0.2 g of hepatic tissue is taken andis manufactured into liver homogenate. The liver homogenate iscentrifuged at the speed of 3000 rpm for ten minutes, and then thesupernatant liquid is removed. The TG content in the supernatant liquidof the homogenate is determined with a biochemistry instrument, and MDA,GSH and protein level in the supernatant liquid of the homogenate aremanually determined according to the method provided in the reagent kit.

Liver Pathological Histology Examination: The left lobe of the liver istaken and is fixed with 4 percent of formaldehyde, and the liver is cutinto pieces through paraffin and ice, dyed through HE and sudan III,examined through microscope and graded.

Data Treatment: The body weight of the mice, TG, MDA, GSH and other dataare all measurement data, the normality test and the homogeneity testfor variance is performed on the initial data through the SPSSstatistical software, the data of MDA and TG are logarithmicallytransformed to ensure the data thereof to meet the requirement of thehomogeneity of variance, then, the solvent analysis is performed throughthe method of one-factor analysis of variance (ANOVA), the statisticaltreatment to the data (P is larger than 0.05) is performed through thepair wise comparative statistics by taking the average number betweenmany experimental groups and a control group. The pathological histologyinspection result is statistically treated through a rank sum test.

Experimental Result: The influence of the composition to the body weightof animals is shown in Table 14.1. There is no real difference (P largerthan 0.05) on the body weight of the mice in all groups before and afterthe experiment. This shows that the composition has no particularinfluence on the body weight increases of the mice.

Table 14.2 shows the influence of the composition on the malondialdehyde(MDA) content in the liver homogenate of the mice. As shown in thisTable, MDA content in the liver homogenate of the mice in the modelcontrol group is increased and has significant difference (P less than0.01) compared with the blank control group, and this shows thatmodeling is successful. In the composition, compared with the modelcontrol group, the MDA in the liver homogenate of the mice in the highdosage group is decreased and has important difference (P less than0.05), and this shows that the MDA content in the liver homogenate ofthe mice with the alcoholic liver injury in the high dosage group can bereduced by adopting the composition of the invention.

Table 14.3 shows the influence of the composition according to theinvention on the reduced glutathione (GSH) content in the liverhomogenate of the mice. Indeed the GSH content in the liver homogenateof the mice in the model control group is reduced and has significantdifference (P less than 0.01) compared with the blank control group, andthis shows that modeling is successful. Compared with the model controlgroup, the GSH content in the liver homogenate of the mice in all thedosage groups is enhanced by adopting the composition of the invention,and the differences are respectively significant (P less than 0.05, Pless than 0.01. This shows that the composition of the invention canenhance the GSH content in the hepatic tissue of the mice with analcoholic liver injury.
